Not sure if I’m pregnant

Hello,

So just as the title says, I’m not sure if I’m pregnant. I’ve taken about 10 strip tests the last week and each of them having a faint line.

The line is the tiniest bit darker now but still extremely faint. I’ve got a different type of test coming tomorrow or Tuesday but I just wondered if this has happened to anyone else and they did turn out to be pregnant?

We’re not trying but had an accident whilst having sex and even tho it’s right after my period. The last time I got pregnant it was because I ovulated right after my period.

It’s been 2 weeks since we had sex.

Thankyou!
